IMPROVEMENT IN DUMPS FORELEVATING AND UNLOADlNG WAGONS.

Specication forming part of Letters Patent No. 213,285, dated March 18,1879; application filed January 9, 1879.

To all whom it may-concern.-

Be it known that I, EDWARD D. HARRI- soN, of Galva, in the county ofHenry and State of Illinois, have invented certain new and usefulImprovements in Dumps for Elevatin g and Unloading Wagons; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure l is a side elevation of a construction Yembodying my invention.Fig. 2 is an end view. Fig. 3 is an elevation in the plane of the linea: x in Fig. 1. Fig. 4 is an elevation in the plane of the line y y inFig. l. Fig. 5 is a detail view, hereinafter referred to, a top plan oithe block E. Fig. 6 is atopplan view.

This invention relates to apparatus for raising and tiltingwagon-bodies, to unload them, and lowering them into place, andconsists, irst, in a suspending-block pivoted to the upper part of thesupporting-frame in suchmanner that it may be turned in a horizontalplane to bring the elevated wagon-body into desired position, and in avertical plane to discharge its contents; second,in a pivotedsuspending-block provided with a gravitatingcatch to hold it inposition, and which is released by the wagon-body striking it whenelevated; third, in a suspending-bar, which can be moved over laterallyto carry the elevated wagon-body to one side, as desired.

The invention further consists in the construction and combination Vofparts hereinafter fully described, and set forth in the claims heretoannexed.

Referring to the drawings by letters, letters A represent four posts,supporting two parallel bars, A. The posts A may be attached to a base,A", and connected by bars A, to form a portable frame, A". B is a barextending from one bar A to the other, and has a head,

B, on each end, each head provided with grooved wheels b, which rest ontracks a', which tracks are xed to the bars A'. C is a shaft journaledin suitable bearings in the heads B', with its ends projecting beyondsaid heads, and each provided with a pinion, o, which gears with arack-bar, c, fixed one to each bar A. D is a pulley on one end of theshaft C, and it has a cord, D', coiled thereon, with both ends extendingdownward to near the lower end of a post, A, where they are looped overa button, D".

It will be evident that by drawing one end of the cord D itscoilfriction on the pulley D will rotate it, and cause the pinions c toact on the rack-bars c', and thus carry the bar B over to one side ofthe frame A" and by drawing the other end ofthe cord D it may be carriedback and to the other side of the frame A". Stops a ou the tracks a willstop the bar B at the desired place.

E is a tilting head-block, pivoted centrally in the arms f of a yoke, F,so that it can be tilted'or either end raised and lowered, and the yokeF has a central standard, f', journaled vertically in the bar B, so asto permit oscillatin g or swinging the head-block E in a horizontalplane. G is a gravitatlng latch or catch, pivoted at g in a slot, e, inthe headblock E, so that its heavier end g will project its lighter endg upward through the block E, where it may engage with a slot, 11', in ablock, b", which projects downward from the bar B, and has its sidestapered or beveled, so that the latch G will slide over either of themto pass to its position in the slot b', when the block E is swung aroundto bring it paralg lel-with the bar B. H is a link, engaged at one endwith a slotted plate, h, on the bar B,

and at its other end with aslotted plate, h', on

the head-block E. The slotted plates 1th can lbe adjusted longitudinallyand held by the screw-bolts shown in the drawings.

The link H will prevent swinging the headl block E, except in thedirection shown by the arrow at Fig. 6 of the drawings; and when thehead-block is tilted, as shown by dotted lines at Fig. 2, the link Hwill limit its inclination, and may be adjusted by the slotted plate hto allow it to incline more or less to a horizontal line, and may bealso adjusted by the slotted plate h, to permit it to swing around moreor less on the pivot f.

The block E is also provided with a series of pulleys, e', in each end.

I is a block similar in shape to the block E,

and it has a similar series of pulleys, t', near'` each end, Aand alsoabar, i', `at each end from the outer ends ot' which hang pendent rods Jthe lower ends of which are formed into eyes y'.

K is a wagon bed or body, with transverse bars 7c, projecting slightlybeyond its sides, and with' its endgate L, having side plates, L', andhinged so that it can be turned down, as shown by dotted lines at Fig.2.

Z l are spring-catches, which extend over and engage with the end-gate Lwhen it is turned up, (closed,) and hold it in place.

M INI are levers, pivoted to the rear side of the end-gate L, and theiradjacent ends connected by a link, fm, so that when drawn downward theirouter ends will strike and raise the catches l', and thereby release theendgate. N is a cord, with a hook, a, on one end.

AP P' are cords passed over the pulleys on the blocks E and I, as shownin the drawings, and so as to obtain differential motion in raising theblock I. The free 'ends of the cords P P' are passed around a pulley, Q,mounted centrally above the block E, and thence over a pulley, R, on oneof the posts A, and downward to a pin near the ground.

In operation, the frain'e A""v is seated near the place T, into the topof which it is desired to discharge the loaded wagon. The wagon may bethen driven to bring its body beneath the block I, when the eyes j onthe rods J may be engaged with the projecting bars k. By drawing on thecords P P' the wagon -body may be elevated until the block I strikes theend g' of the latch G, and thus releases its other end from the blockb", and allows the wagon-body to be swung around on the pivot f' untilthe end-gate is toward the bin T, when the bar B may be moved laterally,as hereinbefore described, to bring the wagon-body so that its end-gateis over the bin T. The'wagonbody maybe then tilted and the end-gatereleased, to allow the load to discharge, by drawing on the cord N,which was engaged with the link m before the wagon-body was elevated.

When the load is discharged and the cord N released the wagon-body willright itself, andV may be then swung-around, so that the latch G willbeagain engaged with the block b", and the wagon-body may then be loweredby the .cords P P' again to its place on the wagon, and the rods Jreleased to allow it to be removed.

The device may be used for unloading earcorn into corn-cribs or forother purposes.

What I'clairn as new is- 1. In combination with elevating apparatus, thehead-block E, suspended so as to be turned in a horizontal plane andtilted in a vertical plane, substantially as and for the purposespecified.

2. The gravitating-latch G, arranged to op erate' with theelevating-cords, and with Ithe block I, tilting-block E, and block b",substantiallyas described, and for the purpose setforth.

3. In combination with the blocks E I and elevating-cords P P', the barB, adjustable laterally on the frame A"", substantially as and for thepurpose specified.

4. The link H and slotted plates 7L h', ar-

ranged to operate with the tilting-block E, block I, and the elevatingdevices, substantially as described, and for the purposeset forth.

5. The shaft C, pinion c, pulley D, and cord D', in combination with thebars A', rack-bars c', bar B, wheels b, and with elevating devices, asand for the purpose specified.

6. The block I, having pendent rods J, with eyes j on their lower ends,in combination with the elevating. devices, and with the wagon-V` bodyhaving projeeting bars 7c, substantially as and for the purposespecified.

In testimony that I claim the foregoing as my own I atlix my signaturein presence of two witnesses. Y
